To IL lit/"loot Ii" 111,171 concern.-

Be it known that i, \Vnuan l/VALLACR Coxovnn. of the city of Toronto, in the county of York, in the Province of Ontario; Canada,

in Improvements in Pneumatic Chraners, of i minimum amount of powe' and afterward i readily discharged.

The invention includes the various features of construction and arrangement and combination of parts-hereinafter described, and particularly pointed out in the appended claims.

I have illustrated the invention in the'occi'iinpanying drawings, in which-- Figure l is a perspective view of my ini roved pneumatic cleaner.. Fig. 2 is a longitudinal section through the cl aner. Fig. 3 a vertical section through the line 11/, Fig. 2, with the ballle-plate removed. Fig. 4 is a cross-section. Fig. 5 is a longitudinal Fig. o is a detail view of oneo'f the casters and sockets therefor.

in the drawings like letters of reference in dicate corresponding parts in earh. ligui e.

A is the main casing, which is substantially rectangular in form. and having a rounded rear end (V.

B and i are the front and hael; boards of the lwllows-easing, secured to the inside of the front and back portions of the main casing, the sides of such inn formed of upward extensions X.

arranged as indicated, and l) and 1d are the top and bottom of tho lmllowsaiasing.

F and h" of the bellows, formed by the front and back board B and (3" and the. central board it and the collapsible material surrounding the boards.

(l is the axle, on the ends of which are socured the wheels (l, theaxle being journaled in suitable bearingsinthc main easing.

H are pitmen conne ted at one end to have invented certain new and use-.

av machine of this class i the by I in casing being The front Z and back B and (3 of the bellows-easing are are the front and back portions l l i l l l I crank-pins on the wheels G and at the opposite end to the pins I, secured in the ends of the division-board and extending through slots'l in the side A J are the handles, which are suitably connected to the axle and are of any suitable form, such handles being designed to impart a bacluvanl-aml-forward movement to the machine. I K K are openings provided with suitable valves R, such openings being located toward each side of the bellows-easing in the front and back, as indicated.

l.- are openings located in the front and back of the bellows-casing. The openings L are approximately double the area of the openings K, or both openings K at each side equal in area the opening 11.

M are inclined conduits extending from the openings L in the bellows-casing upwardly, as indicated, through the main casing and beyond the top of the same. The conduits M are provided w'th l-langes )l of any suitable form and outwardly-ipening valves M N a. bag of any suitable fabric which will allow the air but not the dust to pass through Such bag N is provided with two n'iouths N" and N having elastic bands N which may be expanded so that they may be drawn over the llanges M and then contracted so that they will hug closely the conduits M and prevent the escape of dust.

(l is a drawer, which is provided with ashallew rear porlion O, extending beneath the bello\\'seasing to the rear, such rear portion being curred at the end to (it the curve of the end of the casing. The drawer O is provided with an inclined bathe-plate 0 as indieal ed, located at :1V short distance in front of the bellows-casing. The drawer is also provided. with a depending front having a Hat bottom 0', provided with I r-i'uss-oril'iiiQ t)". The drawer has a eurx ed front ()v which extends over the front edge of llnrasing as shown. The drawer is also preferably provided wilhsides U is a handle by which the drawer may be readily drawn out, and P are spring-calches secured to the front portion of the drawer and provided with holes 1" and knobs P whereby the holes P may be brought over the pins Q in the sides of the easing, so as to secure the drawer in position.

lLi

involved in my invention I shall briefly de- 15 I "the machine, the mouth 0 of the drawer so v to time. The heavier dust particles will re- .main in the drawer'in front of -the baffle casingand leaving a passage underneath the 3 3 L and ivalved conduits M. Any fine dust into and be caught y the ag. 35

c Having now described the princlpal parts scribe its operation andutility.

By drawing backwardly and forwardly, on

being held downwardly close to the carpet .or dust-laden surface by the springpressed caster-wheels, the double bellows acting will cause .a suction through the slot 10 and drawer'and casing, and thereby draw out the dust .11 into the drawer in front of the bafiieplate the air being drawn in throughthe openings K and ejected through the openings 'whichwould still be'in the air would ass into the bag N, the air passing out into t e room and the dust remaining in the bag, from which it may be readily removed from time ;plate,.while the li hter articles will pass What I claim as myinvention is 1 A pneumatic cleaner comprising a'casrig open at its front end; and havin a suct on-chamber located toward the bee of the same, said-passage communicating at opposrteendsby valvedinlet-opcnings with the suction-chamber,- a double-acting suctionl creating device located in the chamber, a

drawer extending into the casing through the open front end and beyond the rearof the suction-chamber and having a deflectingplate located thereon in front of the forward inlet-opening and a dependingfrontmouthpiece, and valved outlet-conduits for the suctioinchamber extending upwardly. from the front and rear of the suction-chamber beyond the top of the casing.

2. A pneumatic cleaner comprising a casing open at its front end and havin a suction-chamber located toward the bac of the casing and leaving a passage-underneath the same, said passage communicating at opposite ends by valved inlet-openings with the suction-chamber, a double-actin suctioncreating device located in the ciarnber, a suitable mouthpiece in the front of the casing and valved outlet-conduits for the suctionchamber extending upwardly from the front and rear beyond the top of the casing, as specified.

3., A pneumatic cleaner comprising a casing open at its front end and having a suctionchamber located toward the back of the casing and leaving a passage underneath'the same, said passage communicating atopposite ends by valved inlet-openings with the suction-chamber, a double-acting suctioncreating device located in the chamber, a defleeting-plate located in the casing in front of the forward inlet-opening, asuitable mouthpiece in. the front of the casing and valved outlet-conduits for the suction-chamber extending upwardly from the front and rear beyond the top of the casing, as specified.
